Adding the option to route requests through a proxy

[Lcchy]

For my use of rsspls I have added the option to route all requests through a proxy url (my home residiential IP, while rsspls runs on a VPS which gets blocked) specified in the [rsspls] section of feeds.toml. It supports socks5, http and https proxies with a quite minimal code change.

Would you be ok with a PR for this feature?

Yes in principle this sounds ok. Does it require extra dependencies?

specified in the [rsspls] section of feeds.toml

My understanding is that proxy settings are typically set in the environment so that each individual program does not need to be configured. It seems like supporting these in preference to or in addition to the config file would be ideal:

• http_proxy
• HTTPS_PROXY

Sounds good! it just adds needs an additional feature to the reqwest create.

I am going to open the PR then.

Ps: FYI I just found out that this also enables using external scraping tools like headless browsers through projects like this:
